The 2-in-1 Bag & Mulch 40V Lawn Mower from Worx has all the power and advantages of a traditional mower, without the drawbacks. Battery-powered mowers are quieter, more efficient and cost effective, and cleaner to use for both you and the environment. And with double the power and double the runtime, this mower offers gas-like performance. As part of the Power Share platform, it uses the same batteries as every other tool, outdoor power and lifestyle product in that family. The two 20V batteries in this model to give it 40V of power, and this version comes with two 4.0 Ah batteries. That~s twice as much charge as the standard 2.0 Ah rechargeable batteries, for twice the runtime. You can mow up to 1/8 acre per charge. And we tossed in a dual-port charger, so you can ~fill up~ quickly. It takes 2 hours to charge both or if you just need one battery for another Worx PowerShare tool, you can charge one in just an hour. This is a modern mower with modern features. Intellicut gives you extra torque when the grass is thicker, and then lets you dial it back down to conserve energy when the terrain is smooth. The six cutting height positions range from 1.5~-4.0~, and the cut-to-edge placement of the blades lets you get closer to the house or garden for less trimming later.
